startBatch method Null safety

Future<Batch> startBatch()

This function will create a Batch object, this allowed you to do some sort of transaction control. example: var b = await jsonStore.startBatch(); await jsonStore.setItem('key', value1, batch: b); await jsonStore.setItem('key', value2, batch: b); await jsonStore.setItem('key', value3, batch: b); await jsonStore.commitBatch(b);

Implementation

Future<Batch> startBatch() async {
  final Database db = await _databaseFuture;
  return db.batch();
}
